A new report commission by the makers of erectile dysfunction medications to calm fears about the reported side effects of common impotence medications has shown that neither Viagra nor Cialis is damaging to the sight. U.S researchers have reported that after six months, healthy men taking one of the two drugs reported no significant vision problems.

The study examined 244 healthy men who had no previous problems with their sight but were experiencing erectile dysfunction. The trial was randomised and designed to find any changes in the retina amongst those taking the medications. 85 took 5 milligrams of Cialis, 77 took 50 milligrams of Viagra, Pfizer’s medication, and 82 were given a placebo. Tests were carried out on their eyes comprehensively, including visual function tests, measurements of pressure and electroretinography, the measurement of electrical responses in the eyes cells.

The scientists acknowledged that their study was limited due the low doses taken by the men, compared with the doses used in some other studies tracking retinal changes. They also warned that as men with existing eye problems were excluded from the study, the results were not applicable to this group.

The market for erectile dysfunction medications is a massive source of money for pharmaceutical companies, with combined sales of the two most popular medications, Cialis online Canada and Viagra, making more than $1 billion globally. Some men prefer to buy Cialis as the effects last longer, but many continue to buy Viagra on the basis of its immediately recognisable brand name. Sales of Levitra, Bayer’s version of the drug, are also considerable though this medication was excluded from the study. Reports of side-effects seriously unnerved the three manufacturers, hence Eli Liley funded the study to discover whether their medication could indeed damage sight.

The reports were also alarming as they heightened the stigma already existing around erectile dysfunction, conjuring up memories of the stories of counterfeit E.D medications being sold over the internet, with the potential to seriously harm men’s health. While there are legal online clinics selling medications with a doctor’s prescription, counterfeit drugs abound. It is therefore in the pharmaceutical industry’s interest to behave as correctly as possible; quickly initiating a clinical trial is an excellent way to allay fears.

However as a relatively small number of men took part and they received a low dose of the treatment, it is to be hoped that more extensive trials will now be initiated. Nonetheless, rumours of side effects are unlikely to put off the millions of men who have had their lives dramatically altered by the advent of treatment for erectile dysfunction.

There are only three FDA approved drugs available for treating erectile dysfunction, Viagra Cialis, or Levitra. All three are designed to get the blood flowing into the penis so that once a man gets sexually stimulated he can obtain and keep an erection. They all work in the same manner to produce an erection but what does vary is the amount of time that they work for and how quickly they work. To many people this is an important factor to be considered.

Comparing Levitra to Viagra, both begin working in about a half an hour but Levitra lasts for about five hours and Viagra lasts for about four hours. Cialis takes effect in as little as fifteen minutes and lasts for up to 36 hours. Because the three drugs are basically one in the same if you try one and it doesn’t work for you for some reason, it is unlikely that any of them will be effective.

If you suffer from prostate problems or from blood pressure issues and are on alpha blockers than it is unlikely that a doctor would recommend Cialis or Levitra online pharmacy because it could cause your blood pressure to drop seriously low. If you are on any forms of nitrates then you will likely not be a candidate for any of the erectile dysfunction medications.

The same considerations will be taken for all three medications if you have had a stroke, an irregular heartbeat or a heart attack. The side effects of all three erectile dysfunction medications are the same. Some of the side effects are a feeling of warmth or flushing, headache, stomach upset, and changes in vision. Often cialis no prescription canada also causes back pain as one of the side effects as well.

While these three medications sound a lot alike there are some significant differences too. Levitra is said to be more potent than Viagra, Cialis is not any less effective if it is taken with a greasy meal such as fast food but the other two are. Basically what it boils down to is lifestyle; there is just enough variation in each of the three medications that choosing which one will be best for you can be decided by evaluating your lifestyle. Only you know when you will need an erection and by doing a bit of research or speaking with your doctor about this you will be able to come up with a choice hat you are comfortable with
